Organic fertilizer and preparation method thereof

Abstract

The invention relates to technical field of organic fertilizer manufacturing, in particular to an organic fertilizer and a preparation method thereof. Mixing in proportion is performed through distilled grains, edible mushroom culture medium and chicken manure, so that the nutritive value of the organic fertilizer is guaranteed, the waste chicken manure, edible mushroom culture medium and distilled grains can be utilized, and then the organic fertilizer is produced as a product with a greater added value, the environmental pollution is avoided, and the production cost of the organic fertilizer; moreover, concentrated sulfuric acid is added in the preparation process, and the concentrated sulfuric acid is instantly heated after meeting water, so that the initial fermentation time is shortened in the raw material stockpiling process, the preparation cycle of the organic fertilizer is shortened, particularly heat generated in the heating process through water absorption of the concentrated sulfuric acid meets the heat requirement of the fermentation process, and the energy consumption in the preparation process of traditional organic fertilizers is reduced; and moreover, the heat discharged through the water absorption of the concentrated sulfuric acid is used for performing sterilization treatment on harmful germs in the chicken manure, and the quality of manufacturing the organic fertilizer by the chicken manure is improved.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer production, in particular to an organic fertilizer and a preparation method thereof. Background technique [0002] Organic fertilizers are rich in organic matter and nutrients needed for crop growth. They can not only provide the nutrients needed for crop growth, improve the soil, but also improve crop quality, increase crop yield, promote high and stable crop yields, maintain soil fertility, and increase fertilizer efficiency. Utilization rate, reduce production cost. The full and rational use of organic fertilizers can increase crop yields, improve soil fertility, improve the quality of agricultural products, and increase the effectiveness of soil nutrients. Therefore, the promotion and application of organic fertilizers in our country is in line with the requirements of "accelerating the construction of a resource-saving and environment-friendly society", which will promote the harm...

Problems solved by technology

However, because some bacteria contained in chicken manure are difficult to be killed by the temperature generated by fermentation, a large number of bacteria still remain in the produced organic fertilizer, and after fertilization is applied to the soil, it will bring a lot of bacteria to the soil. Infection of pathogenic bacteria, which in turn leads to crop yield reduction; especially harmful roundworms, roundworm eggs, and fecal coliform bacteria in chicken manure are difficult to kill during the fermentation process of making organic fertilizers, which in turn leads to farmland diseases and insect pests. The specific performance is that the crops may have problems such as fruit ulcers and root infections; at the same time, during the fermentation process of traditional organic fertilizers, heat is generated by external heating or raw material stacking, and then fermentation is promoted by heat. This leads to longer production cycle of organic fertilizer, higher energy consumption and higher cost
